and S5, acquiring the current surface type of the workpiece to be processed.
Specifically, the surface shape accuracy of the roughly machined workpiece to be machined can be measured by using a high-accuracy optical detection instrument.
And S6, comparing the current surface type with the target surface type to obtain the surface type error of the workpiece to be processed.
After the surface type error of the workpiece to be processed is obtained, the removal amount of the workpiece to be processed can be determined, so that the workpiece to be processed can be processed by utilizing the ultra-precise structure.
The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
